wavevar: Wavelet variance analysis

Description

Calculates the wavelet variance based on a wavelet multiresolution analysis.

Usage

wavevar(f, coord, wavelet = "haar", wtrafo = "dwt")

Arguments

f

A vector

coord

A matrix of two columns with corresponding cartesian coordinates. Currently only supports integer coordinates.

wavelet

Name of wavelet family. haar, d4, and la8. are possible. haar is the default.

wtrafo

Type of wavelet transform. Either dwt or modwt. dwt is the default.

Value

Wavelet variance for f.

Examples

# NOT RUN {
data(carlinadata)

coords <- carlinadata[ ,4:5]
pv <- covar.plot(carlina.horrida ~ aridity + land.use,
                 data = carlinadata,
                 coord = coords,
                 wavelet = 'd4',
                 wtrafo = 'modwt',
                 plot = 'var')
